Subject: (ET) Polarity and Installing Batteries

I have an E-12 and am .about to install the batteries. The 2 in the front are
in correctly.
Under the seat there are 2 main cables, but how can I test to see which is
pos and which is neg? One of the cables has a thinner wire attached to it.
Also there is another thin wire that  goes someplace. I need some advice.  

 

 

 

If the thing hasn't been modified, the wiring should be about like this:

 

At the moment, the wire from your power disconnect should be connected to the + 

side of the back battery of front pair of batteries (B2) under the front hood.  You 

should already have a heavy jumper running from the - of that battery (B2) to the + 

on the front most battery (B1).  Now it gets interesting.

 

The - lead from the front most battery (B1) runs through a hole under the charger 

area and all the way to the back under the seat.  The wire is labeled 00.  The hole

is on the right from the driver's seat.  It should appear to be the SHORTER of the

two heavy leads as far the the part protruding from under the tractor and into the

box under the seat.  You can check to see with an ohm-meter to make sure it

goes to the - of B1.  That long lead comes out on the right side (again from seated position) and connects up to the + terminal of the of the right-side

(from the seat) front most battery under the seat (B3).  The - from that battery (B3)

goes to a heavy jumper and to the forward left battery + (B4).  A heavy jumper runs

from the - of B4 straight back to the rear left battery (B6) + terminal.  Another heavy

jumper goes from B6 - to the + on the right rear battery (B5).  Finally, another long

wire runs from the right rear battery - (B5) to the panel area; this wire is labeled 4

and goes to the 2F connector.

 

The lift (very light wire) runs to the point between B3 and B4, that is the - of B3 or 

the + of B4 (it doesn't matter) while the other side of the lift is at the panel.

 

Look for 36 to 41 V between the + of B2 (rear battery under front hood) and - of B5

(rear right battery) to check yourself.

 

I guess I need to keep a scanned schematic on hand.  I can try tomorrow.
